Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The material preview method based on the server provided by the invention can be applied to an application environment as shown in figure 1, wherein a local playing end is in communication connection with a main server and a secondary server; the remote playing end is in communication connection with the secondary server, and the local playing end and the remote playing end can be understood as video software arranged in the server.
In an embodiment, as shown in fig. 2, a method for previewing a material based on a server is provided, and the method is applied to a material playing system composed of a master server and at least one slave server in fig. 1, wherein the master server and the slave server are in communication connection, and the method includes the following steps S10-S20:
s10, when at least one slave server receives a material preview instruction sent by the master server, a first original material is played at a remote playing end corresponding to the slave server receiving the material preview instruction;
understandably, the first raw material is a video material corresponding to a remote playing end of the secondary server, and the low-code stream material corresponding to the first raw material is a video material corresponding to a local playing end of the primary server; the material preview instruction is an instruction (low-code stream material preview mode) sent from a local playing end in a main server, and the low-code stream material and the second raw material corresponding to the first raw material can be displayed on a display interface corresponding to the local playing end through the instruction, wherein in the display interface, the materials can be displayed through a display window, the size of the display window can be adaptively set according to the resolution of the video material, and the number of the display windows can be adaptively set according to the number of the video materials; in this embodiment, when the secondary server receives the material preview instruction, the remote playing end may play the first raw material, and the local playing end may play the low-code stream material corresponding to the first raw material in the manner of step S20.
S20, the local playing end corresponding to the main server synchronously plays the low-code stream material and the second original material corresponding to the first original material so as to realize synchronous material preview of the low-code stream material and the second original material at the main server; the first raw material and the second raw material are derived from the same material or different materials.
Understandably, the second source material may be a video material composed of the first source material corresponding to each secondary server, a video material composed of the first source material corresponding to the secondary server (the video materials corresponding to all secondary servers are identical), or a video material completely different from the secondary server; the method comprises the steps that a communication connection relation exists between a main server and a secondary server, a local playing end of the main server bears the function of controlling all the secondary servers and the main server, namely when a video material playing instruction is issued to all the servers in the local playing end of the main server, corresponding video materials (including an LED display screen and a computer screen) are required to be played by display screens (including display screens corresponding to the main server) connected with the secondary server, second raw materials are played by display screens corresponding to the main server, and first raw materials are played by display screens corresponding to all the secondary servers; in the local playing end of the main server, when a material preview instruction is issued to all the servers (in addition, according to specific conditions, a preset number of secondary servers can be selected from the secondary servers playing video materials to issue the material preview instruction according to specific requirements), a display screen connected with the main server and the secondary servers (all the display screens corresponding to the main server are required to play the first original material, the display screens corresponding to the secondary servers play the low-code stream material corresponding to the first original material;
In this embodiment, when the local playing end in the main server previews the material, the second original material corresponding to the main server has already completed screen (LED screen), that is, the second original material has already been decoded and encoded in the local playing end, so that the material previewed by the local playing end in the main server is the second original material, the performance of the main server is not required to be reduced by decoding and encoding, and the decoding and encoding of the first original material corresponding to each secondary server is implemented by each secondary server, so that the material previewed by the local playing end in the main server is the low-code stream material corresponding to the first original material, and the low-code stream material needs to be decoded and encoded;
in another embodiment, the local play end of the main server may also preview any one of the low-code stream material and the second original material.
In the embodiments of steps S10 to S20, when playing the material, after the high-resolution first raw material corresponding to the plurality of secondary servers is mainly converted into the low-code stream material, the low-code stream material and the second raw material corresponding to the primary server are synchronously played through the local playing end of the primary server, so that the synchronous material preview (including the video material corresponding to the primary server and the secondary server) can be realized at the local playing end of the primary server, and the load and pressure of the primary server can be reduced (the performance of the primary server is reduced).
Further, the local playing end corresponding to the main server synchronously plays the low-code stream material and the second raw material corresponding to the first raw material, which comprises:
the main server acquires the low-code stream material corresponding to the transcoded first original material, decodes and encodes the low-code stream material, and plays the encoded low-code stream material at the local play end;
and simultaneously, after the main server confirms that the second original material is decoded and encoded, the second original material is played at the local playing end.
As can be appreciated, in the process of implementing the above-mentioned material preview by the main server, the material needs to be decoded and encoded (the decoding is a local decoding manner, that is, the main server only decodes the low-code stream material of the first raw material corresponding to each secondary server, and the low-code stream material must be displayed in the local playing end of the main server), but because the main server has implemented the decoding and encoding of the second raw material in the process of playing the material, the embodiment can implement playing of the second raw material after confirming that the second raw material completes decoding and encoding; in particular, the manner of decoding and encoding is consistent with the above, and not described in detail herein, the decoding process may be generally divided into channel transmission-entropy decoding-inverse quantization-inverse transformation-prediction, and the encoding process may be generally divided into prediction-transformation-quantization-entropy encoding; in this embodiment, the slave server does not need to transmit the first raw material back to the master server through a network or the like, and occupies the performances of the master server and the secondary server.
In another embodiment, the obtaining, by the main server, the low-code stream material corresponding to the transcoded first raw material includes: the main server judges whether the video played by the local playing end is a low-code stream material or not; if the video is a low-code stream material, the main server acquires the low-code stream material corresponding to the first original material after transcoding; and if the video is not the low-code stream material, the local playing end plays a preset software pattern.
Further, before the main server obtains the low-code stream material corresponding to the transcoded first original material, the method further includes:
and generating the low-code stream material according to the first original material, binding the low-code stream material with the first original material, and determining that the low-code stream material is imported into the local playing end.
Understandably, a material binding window is arranged at the local playing end, and whether the generation mode of the low-code stream material is transcoding from a third-party transcoding platform or autonomous transcoding from video software, the low-code stream material and the first original material can be bound through the material binding window; specifically, after the first raw material is added to the far-end playing end, a first raw material array named by a first array is generated, after the low-code stream material is added to the material binding window, a low-code stream material array consistent with the naming of the first array is generated so as to finish the binding of the first raw material of the low-code stream material, if the first raw material array named by the first array can be a [ 0 ], the low-code stream material array named by the first array can be a [ 1 ], and the array of the second raw material can be b [ 0 ]; after the binding is achieved, the embodiment finishes importing the low-code stream material into the local playing end.
In another embodiment, the generating the low-code stream material according to the first raw material, binding the low-code stream material with the first raw material, and determining that the low-code stream material is imported into the local play end includes: the first original material is imported into a local playing end of the main server; after the successful importing is determined, the low-code stream material is generated according to the first original material, and the low-code stream material is imported into the local playing end after being bound with the first original material, so that the low-code stream material is imported into the local playing end; in this embodiment, the local playing end of the main server has a limitation on the maximum video playing and processing capability, and when a high-code stream first source material, such as 8K, is successfully imported into the local playing end, it is determined that a low-code stream material, such as 2K, can be successfully imported into the local playing end.
Further, the generating the low-code stream material according to the first raw material, binding the low-code stream material with the first raw material, and determining that the low-code stream material is imported into the local playing end further includes:
Acquiring a first time length of the low-code stream material;
acquiring a second time length of the first raw material;
when the difference value between the first time length and the second time length exceeds the preset time length, prompting that the low-code stream material is not the low-code stream material corresponding to the first original material after transcoding;
and when the difference value between the first time length and the second time length is not more than the preset time length, generating the low-code stream material according to the first original material, binding the low-code stream material with the first original material, and then determining that the low-code stream material is imported into the local playing end.
Understandably, the first time length and the second time length refer to time lengths corresponding to playing time of the material, and after transcoding is performed by the third transcoding platform and the local playing end, the first time length and the second time length are generally equal or have small phase difference; in the embodiment, whether the low-code stream material added to the material binding window corresponds to the first original material is confirmed by comparing the difference value of the time lengths, when the correspondence is confirmed, the low-code stream material is substituted into the local playing end, the process of previewing the low-code stream material is realized, when the correspondence is confirmed, the fact that the low-code stream material does not have a corresponding relation with the first original material is prompted in a highlighting mode, and the situation that the local playing end in the main server previews wrong material contents is avoided.
Further, after the step S20, the method for previewing server-based material further includes:
when the first original material and the second original material are different materials, determining whether a local playing end corresponding to the master server starts a back display function or not and whether at least one remote playing end corresponding to the slave server starts the back display function or not; the back display function means that a terminal connected with the master server displays the first original material and the slave server displays the second original material, and a local playing end of the master server and a remote playing end of the slave server display low-code stream materials;
when the main server and the auxiliary servers are determined to start the back display function, at least one auxiliary server plays the low-code stream material corresponding to the first original material at a corresponding remote play end;
and synchronously playing the low-code stream material corresponding to the first original material and the second original material at the corresponding local playing end by the main server.
Understandably, the back display function is a relationship between three devices, such as an LED display screen, a server, and a terminal (a computer screen connected to the server), where in the three relationships, the LED display screen displays raw materials, the terminal displays low-code materials, and a playing end in the server is used for controlling playing materials; the method comprises the steps that a primary server and a secondary server are placed, a first original material is displayed on an LED display screen connected with the secondary server, a low-code stream material of the first original material is played on a far-end playing end corresponding to the secondary server, a second original material is displayed on an LED display screen connected with the primary server, but a local playing end corresponding to the primary server still plays the second original material and the low-code stream material corresponding to the first original material (the method is required to be described, when the low-code stream material is played on the primary server, a computer screen corresponding to the far-end playing end still plays the first original material); when the main server of the embodiment starts the playback function, the second original material is played at the local playing end, because the second original material has finished decoding and encoding, the performance of the main server is not occupied any more, and in order to ensure the display effect, the local playing end plays or plays the second original material with high code stream (high resolution);
In another embodiment, the main server may not be connected to a terminal, but the second source material may be played in a local play end of the main server.
In another embodiment, before the determining that the first raw material and the second raw material are different materials, the method further includes: the secondary server judges whether a video (a first raw material) is played at the terminal; if the video is not played at the terminal, the remote playing end does not play the video; if the video is played at the terminal, the secondary server judges whether the video played by the remote playing end is a low-code stream material or not; if the video is a low-code stream material, the remote end of the secondary server plays the low-code stream material by a play end; and if the video is not the low-code stream material, the remote playing end plays the preset software pattern.
In another embodiment, before the determining that the master server and the slave server both turn on the echo function, the method further includes: when the main server and the auxiliary servers are determined to not start the playback function or the main server is determined to start the playback function, at least one auxiliary server plays the first original material at a corresponding remote play end when at least one auxiliary server does not start the playback function; the main server synchronously plays the low-code stream material corresponding to the first original material and the second original material at the corresponding local play end;
In another embodiment, before the determining that the master server and the slave server both turn on the echo function, the method further includes: when determining that the main server does not start the playback function, at least one slave server starts the playback function, and at least one slave server plays low-code stream materials corresponding to the first raw materials at a corresponding remote play end; and synchronously playing the low-code stream material corresponding to the first original material and the second original material at the corresponding local playing end by the main server.
Further, before the determining that the first raw material and the second raw material are different materials, the server-based material preview method further includes:
when the first original material and the second original material are the same material, determining whether a local playing end corresponding to the master server starts a back display function or not and whether at least one remote playing end corresponding to the slave server starts the back display function or not;

And the main server synchronously plays the first original material and the second original material at the corresponding local playing end.
When the main server of the embodiment does not start the playback function, the local playback end of the main server plays the second raw material because decoding and encoding are completed in the process of playing the video material on the screen, so that the local playback end still plays the second raw material, and the local playback end of the main server previews the first raw material corresponding to the secondary server because the first raw material and the second raw material are the same material, and completes decoding and encoding the first raw material, so that even if the main server does not start the playback function, the local playback end still plays the second raw material.
In another embodiment, before the determining that the playback function is not started by the master server and the playback function is started by the remote playing end corresponding to at least one slave server, the method further includes: when the fact that the playback function is not started by the remote playing end corresponding to the master server and the slave servers is determined, or when the fact that the playback function is started by the master server and the playback function is not started by the remote playing end corresponding to at least one slave server is determined, at least one slave server plays the first raw material at the corresponding remote playing end; the main server synchronously plays the first original material and the second original material at the corresponding local playing end;
